PHP Type Casting

PHP Type Casting

The term "Casting" refers to conversion of one type of data to another. Since PHP is a weakly typed language, the parser coerces certain data types into others while performing certain operations. For example, a string having digits is converted to integer if it is one of the operands involved in the addition operation.

Casting in PHP is done with these statements:


• (string) - Converts to data type String
• (int) - Converts to data type Integer
• (float) - Converts to data type Float
• (bool) - Converts to data type Boolean
• (array) - Converts to data type Array
• (object) - Converts to data type Object
• (unset) - Converts to data type NULL
